Vehicle-mounted device and method for real-time online assessment of micro-distance video image of soil body structural evolution

Abstract

The invention discloses a vehicle-mounted device and method for real-time online assessment of a micro-distance video image of soil body structural evolution. The device comprises a vehicle body, a telescoping device, a micro-distance video image acquisition device, a telescoping device controller and a computer. The method comprises the steps of first establishing a micro-distance video grayscale image database; then establishing a corresponding relationship between each substance and each grayscale value interval in the database; then counting the number of pixels in each grayscale value interval which represents each substance in the micro-distance video grayscale image and establishing a relationship with the content or form of the corresponding subtance; and finally, determining apractical actual characteristic parameter of a to-be-detected soil body based on the abovementioned relationship, and further determining a development state of the soil body. According to the device and method, on-site soil sample micro-distance video assessment is carried out directly, and the test precision is high; and a micro-distance video image is adopted, so that identification of the compositions and the evolution of the soil body is more precise. By wide-range long-term continuous real-time online monitoring of the soil body in a certain area, the evolution rule of the soil body in the area is obtained.

Description

technical field [0001] The invention belongs to the technical field of soil evolution monitoring, and in particular relates to a real-time on-line evaluation device and method for vehicle-mounted macro video images of soil structure evolution. Background technique [0002] At present, the monitoring of soil microstructure evolution mainly adopts the field test method mainly based on manual measurement, which has low efficiency, low precision and large manual error. Because this method needs to transport the soil sample from the field back to the laboratory for testing; on the one hand, after the soil sample is taken out from the ground, the stress acting on it will change; on the other hand, the soil sample During transportation, the properties of the soil will change; these reasons will lead to inaccurate final test results. [0003] With the rapid development of information technology, image processing technology has provided an unprecedented technical means for the devel...

Problems solved by technology

[0004] However, when the existing image acquisition equipment captures images, it is easily affected by natural conditions (such as rain and snow, haze, dust, sunlight intensity and electromagnetic interference, etc.), resulting in poor clarity and resolution of the captured images
